Description

This 40GBASE-ER4 QSFP+ transceiver is built for long-reach 40 Gigabit Ethernet links over duplex single-mode fibre. It suits data centre interconnect and campus or metro links where the fibre run is too long for LR4 optics.

It uses a duplex LC connector over SMF G.652 fibre and reaches up to 40km. Links beyond 30km are engineered links under IEEE 802.3. Transmit power is -2.7 to +3.8 dBm per lane and receive power is -21.2 to -4.5 dBm per lane. Maximum power consumption is 3.5 W. Optical attenuation is required on shorter links to protect the receiver from permanent damage.

The module fits QSFP+ ports on Arista switches. Check Arista's transceiver compatibility matrix for your specific platform and EOS version before ordering.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: What fibre does this transceiver need?
A: It needs duplex single-mode fibre (SMF G.652) terminated with LC connectors. It is not designed for multimode fibre.

Q: How far can it reach?
A: It supports links up to 40km. Under IEEE 802.3, links beyond 30km over single-mode fibre are engineered links, so the optical budget should be planned for the run.

Q: Do I need an attenuator on short links?
A: Yes. Proper optical attenuation is required on shorter links to protect the receiver from permanent damage. The receive power range is -21.2 to -4.5 dBm per lane.

Q: How much power does it draw?
A: Maximum power consumption is 3.5 W per module.

Q: Which switches does it work with?
A: It fits QSFP+ ports on Arista switches. Check Arista's transceiver compatibility matrix for your platform and EOS version.
